VOLUME-REDUCING AND SOLIDIFYING DEVICE FOR WASTE

摘要

PROBLEM TO BE SOLVED: To process and solidify waste regardless of the kind and the characteristics of raw materials such as refuse by a method wherein the pitch of a screw is made larger in the vicinity of a charging port for raw materials, and smaller in the vicinity of the leading end of the screw, and the shaft diameter of the shaft part of the screw is made larger on the leading end side than the vicinity of the charging port. SOLUTION: A sprocket 9 is fixed to a spindle 5. The rotating force of a motor is transmitted to the sprocket 9 through a chain. A screw 1 which is connected to the spindle rotates at a fixed location, and transfers raw materials which are charged in a body A by the rotation of a spiral rotating blade 102 toward the leading end side of the body A while crushing the raw materials. The screw 1 is formed in such a manner that the attaching pitch of the rotating blade 102 to the shaft 101 is made larger in the vicinity of a charging port 8 and smaller in the vicinity of the leading end. The shaft diameter of the shaft 101 is formed in a manner to become larger in the vicinity of the leading end. Also, the shaft diameter of the shaft 101 is formed in a manner to become larger in the vicinity of the leading end compared with the charging port 8. By this method, in the vicinity of the charging port 8, a large raw material can be received.
